' Application ined June 1o, 191s. serial No. 239,153.

Y To all whom t may concern f Be it known that I, JOHN B. WEST, 'a citizen of the. United States, and a resident of Syracuse, in the fcounty of Onondaga and State of New York, have invented nevi,T

Vand useful Automatic Auxiliary Air Valves for Internal-Combustion Engines, of which the following is a specification This invention has for its object an elec-l trically operated air valve for internal combustion engines of the type of valve described in my pending application, Sr. No.

v 193,393, filed' September 26, 1917, which air valve is simpler in construction, more economical in 'manufacture than the valve of my pending application, and which also ycan be made by automatic machinery. Other objects appear throughout the specification.y The'invention consists in the combinations and .constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figures 1 and 2 are respectively an ele' vation and a: vertical sectional view of my air valve the bracket being omitted in Fig. 2. Figure 3 is an end view of the valve piece. Figure 4 is a face view of the supporting bracket and contiguous part.

`Figure 5 is a diagrammatic view showing one way of making the electrical connection A-with the generator circuit.

A one way ofA applying my invention to an View illustrating .my auxiliary air device` connected in the pipe 'of vthe vacuum feed sys'tem. l

This auxiliary valve' comprises generally,

a hollow body formed with .inlet and Aoutlet ports in one portion thereof, electromagnet.

windings around -another portion of the body, a valvepiece within the-body to control said ports, an armature or core within the body and, connected to the valve and preferably forming the extension thereof, and means for limiting the movement of the core to control the extent ofthe opening movement of the Valve and for 4holding the valve open.

The body ishere shown as in the 'form of a tube 1 having inlet and outletports 2, 3 opening through "the lower portion thereof.

4 are the electromagnet windings around the intermediate portion of the body 1, these windings being usually made upon a spool which is placed upon the body between two heads 5,

.7 is a valve casing cylindrical in general outline and having an intermediate trans-- verse partition 8 formed with a threaded opening which threads upon the lower `threaded portion of the body luntil the partition is located between the ports 2,.3,l 'which are spaced apart in a direction lengthwise of the bodyl, this partition separating the casing into inlet and outlet charlibers 9, 10 below and above the partition 8. The upper end of the casing isclosed by a head or nut 11 which is placed on the tubula'r body 1 before the casing 7 is placedl on the body, and the lower end ofthe casing is closed byv a similar head or nut 12 threading on the body against the lower end of the casing. The casing is also provided-with suitableinlet yand outlet ports 13, 14 to which' theV pipes may be 'connected in any suitable manner as by a coupling 15, the'in`l let port beingv connected to a pipe .15a for conductinghot air4 to the inlet chamber 2 and thev outlet port 14 being coinected by a pipe as 16 ,to the intake manifold.

, 17 designates the core located in/fthe tubuf lar body 1 and extending into the-portion thereof encircled by the magnet windings 4. This core is formed with an integral extension extending into the casing 7 and constituting the valve 18. The valve is formed with a reduced portion 19 and with faces 20 and 21 at ,opposite ends 0f the reduced portion which faces serve to balance the` valve so that it is not affected by the suction in the engine cylinder. In other words, the valve isV a`^^balanced valve.

To further facilitate balancing foil the valve so that the'only factor to be taken into consideration is the current; passing through fthe electromagnet, ythe lower lend of the yvalve is formedV with a portion or transverse rib 22 which rests "upon an abutment or plug l23in the lower. end of the tubular body, this 'plug being formed with an air' periphery ofk n the the tube between the faces 20 and 21, outletY the magnet 4 and gravity.V

vent 24. By reason of the rib 22 in conjunction with thefaces 20, 21, the valve is rendered perfectly balanced against the suction in the cylinders so that the only factors in the operation thereof are the pull of The full p0rtion of the valve 18 directly above the reduced portion19 normally covers the outlet port 3 of the body, and when the magnet is suiiciently energized this/port 2 is uncovered So that the air is drawn by suction in the engine cylinders through the port 13, chamber 9, port 2, through the portion of port 3, chamber 10, outlet pipe 16 to the manifold.

As before stated, the magnet is preferably wound on a'spool and placed on the tube against the head 5 and a -head or :nut 25 turns on the body 41 against the lower head 6 anda nut 26 screws onvthe upper end of the body against the 11pper head 5. These nuts 25., 26 may be manipulated to adjust the'relative position of the magnet and core, toregulate the pull of the magnet on the core sothat the device can be adjusted to operate at different amperages. But I prefer to make this adjustment by the use of the sections 34 here. inafter described.

The head 5 is provided with binding posts I 27, 28 connected to the opposite ends of the magnet windings.

The amount of movement of the valve is controlled or limited adjustable means on the upper end of the hotly `1 and carrying a stop arranged in the -pathof the core 17 or the extension 29 thereof.

This means is here shown .as a cap 30 threading on the upper end of the tubular body 1 and carrying a screw 31 threading in the top ofthe cap. q

.The body 1, casing 7, heads 1'1, 12 and 5 and 6, and cap 30 are formed of a non-mag.

regulated. The cap 30 is held in its adjusted `position by a spring v`pressed retaining member, 33. To adjust the valve piece to operate at' different amperages, the Vvalve may be provided with one or more sections 34 or perforated plugs before referred to,

which are placed on the extension 29 of theY core. These may be non-magnetic and act to additionallywmght the core or may be magnetic, and as they are arrangedon the opposite side of the center of the magnetfrom that on which the greater part of the core and valve are arranged, serve to raise the center of the core relatively to the center of the magnet so that a current of greater amperage is required to lift the core and valve than when the core is unprovided with said sections. As here illustrated, said seotions thread onthe extension 29 of the core.

As here shown, there are two sections for the S purpose of screwing one againstv the other jamb nut fashion to positively hold them in adjusted position.

In Fig. 5 is shown a diagram of the electrical connection of this air'y valve. 35 designates the engine, 36 the generator, and 36 the automatic out out or circuitbreaker between the generator and the storage battery 37. 38 is the lighting circuit or load circuit. The binding posts 27, 28 are connected in one of the leads from the generator between the generator andthe automatic cut out 36. i

In Fig. 6, 35a and 35b designate the engine and magneto of a Ford power plant." 38a is the load or lighting circuit and 27, 28, thev binding posts of the magnet of my valve, the magneto, load circuit and magnet Vbeing grounded.

This device may be supported on the enginey by thfe pipe threading into the manifold of the engine or may be -supported by a bracket 40 which maybe attached to the engine any place there is a bolt or screw as one of the screws 40awhich connects the head of the engine cylinders to the cylinders as seen in Fig. 7 f or to one ofthe screws 41 by means of which the carburetor is bolted to the intake manifold as seen in Fig. 7. The bracklet has an opening through which the tubular body 1 extends, and the body is secured' to the bracket in any suitable manner `as by a nut 42.

In engines in which the manifold is enclosed, it is preferable to couple the inlet 14 at the same opening where the vacuum pipe 420 of the gasoline feed is connected. As shown diagrammatically in Fig. 8 the' vacuum pipe-420 and my` ydevice 43 are con;

nected to different branches 42a., 43 ofthe coupling, the third branch 44 of which' is connected to the manifold.

The valve is also preferably provided with" an additional air inlet opening for cold air here shown as a valve 45 eommumcatmg iis with the inlet chamber 9 of the casing 7 and having a cap 46 rotatable to bring a hole 47 therein into and out of alinement with a hole 48 in the body of said valve 45.

In operation, when the engine reaches a predetermined speed and hence the current generated by the generator 36 reaches a predetermined valuev the magnet-4 will be f energized to `lift the core 17 and cause the valve 18 to uncover the port 2 so that auxiliary air enters the casing 7 and passes into the engine cylinders. The value of the current required varies in diiferent power plants and the device is adjusted to diferent power plants by means of the `sections 34, `or by shifting the` magnet lengthwise of the body 1. Also vibration of the valve and core is prevented by means of the 'supplemental magnet 31. This magnet 31 also tends to hold the valve open ntil the amperage has dropped a predeterminedamount, l for instance in some engines the valve opens when" 'the engine running fast enough tofcause the generator to produce a current -of eight amperes and by reasons of the magnet 31 the valve will be held open until the engine runs slow enough to produce sayonly 6 amperes.

Most internal combustionl engine power plants use a generator which produces adirect current. In the Ford cars, the. magneto produces an alternating current and the-.device when applied to Ford' cars requires a magnet windlng of a different size wire from the windingspf the device. adapted for other cars.
